Pathwise uniqueness for stochastic reaction-diffusion equations in Banach spaces with an H\"{o}lder drift component

We prove pathwise uniqueness for an abstract stochastic reaction-diffusion equation in Banach spaces. The drift contains a bounded H\"{o}lder term; in spite of this, due to the space-time white noise it is possible to prove pathwise uniqueness. The proof is based on a detailed analysis of the associated Kolmogorov equation. The model includes examples not covered by the previous works based on Hilbert spaces or concrete SPDEs

The abandoned antimony-mines of SE Sardinia: impact on surface waters

This study investigates the impact of abandoned Sb-mines on the Flumendosa River, which is the most important water resource in southern Sardinia. Hydrogeochemical surveys carried out in 2005 and 2006 indicated a significant impact of waters flowing out from adits, slag, tailings and waste materials on surface waters. The contaminated waters show alkaline pH, and high dissolved SO4, Sb and As (up to 1900, 9.6 and 3.5 mg/L, respectively). Although the flow rates of drainages from the mining area are usually low (in the range of < 0.1 to 1 L/s), the contribution to dissolved concentrations of Sb in the streams downstream of mines is high. Sampling under high flow conditions in the Flumendosa River before the confluence with the contaminated streams showed Sb concentrations below the limits established by the guidelines of World Health Organization for drinking water (i.e. 20 g/L), while downstream of the confluence dissolved Sb was 32 g/L. Contamination in the Flumendosa extended 16 km, and attenuation (15 g/L Sb) was only observed close to the Flumendosa mouth

Romance Tiempo de Silencio Como Painel Histórico dos Desdobramentos Políticos e Culturais da Guerra Civil Espanhola

IX Congresso Brasileiro de Hispanistas realizado nos dias 22 a 25 agosto 2016Esta comunicação, sobre o romance da pósguerra civil espanhola Tiempo de Silencio , se detém na análise daqueles aspectos da obra que contribuem para conformar um painel da sociedade espanhola dos anos 40, especificamente os que apontam para a degradação física e moral de sua população, para seu empobrecimento financeiro e cultural, para a Espanha calada e amordaçada pelos ditames e imposições do regime ditatorial que se implantou no país ao término da dilacerante luta fratricida de 1936 a 1939. Este romance, escrito ao final dos anos 50 e publicado em 1962, sofreu cortes da censura ditatorial e seu autor, Luis MartínSantos, (n.1924 – 1964) enfrentou também o rigor ditatorial nas experiências vividas nos calabouços franquistas. Este intelectual, inserido na cultura de seu tempo histórico, esse artista, engajado e comprometido com a realidade social e política de seu país, propõe em seu texto que seu leitor empreenda uma caminhada pelos espaços degradados da sociedade espanhola na qual se movem seus personagens. Luis Martín- Santos busca romper o silêncio imposto à sociedade espanhola através do emprego de mitos em seu discurso, uma máscara de mitos, fórmula com a qual pode dizer o interdito e aludir, disfarçadamente, àquela realidade social que seu autor deseja ver desvelada por seus leitoresUNILA­-UNIOEST

Prognostic factors of survival in patients treated with nab-paclitaxel plus gemcitabine regimen for advanced or metastatic pancreatic cancer: A single institutional experience.

The objectives of this study were to evaluate the effectiveness of nab-paclitaxel plus gemcitabine (NAB-P/GEM) regimen in an unselected population of patients with advanced inoperable or metastatic pancreatic cancer (PC), and to identify the prognostic factors influencing overall survival (OS). EXPERIMENTAL DESIGN: Patients with age < 85 years, ECOG-performance status (PS) < 3, and adequate renal, hepatic and hematologic function were eligible. NAB-P (125 mg/m2) and GEM (1000 mg/m2) day 1,8,15 every 4 weeks were employed for 3-6 cycles or until highest response. RESULTS: Overall, 147 cycles (median 4, range 1-11 cycles) were administered on thirty-seven consecutive patients (median 66 years old, range 40-82) treated. The median overall progression-free survival and OS were 6.2 and 9.2 months, respectively. The G 3-4 dose-limiting toxicity were neutropenia (20.7%), severe anemia (17.2%), and cardiovascular toxicity (10.3%). PS, number of cycles, baseline CA 19-9 and LDH serum levels, were found to be significantly related to OS. The multivariate analysis showed that both number of cycles (HR = 9.14, 95% CI 1.84-45.50, p = 0.001) and PS (HR = 13.18, 95% CI 2.73-63.71, p = 0.001) were independently associated with OS. CONCLUSION: NAB-P/GEM regimen should be used in all patients with advanced or metastatic PC, with the exception of those with serious contraindications to chemotherapy, such as severe renal or hepatic impairment or major cardiovascular diseases

San Vicente Ferrer (1350-1419) y la eficacia filosófica y retórica del sermón: Arte y Filosofía

O objetivo deste trabalho é analisar alguns aspectos do discurso filosófico e dos elementos da retórica medieval contidos nos sermões de São Vicente Ferrer (1350-1419), sobretudo suas reflexões sobre um tema presente, de forma corrente e universal, na Idade Média cristã: o das virtudes morais, ou virtudes cardeais. Utilizaremos, para isso, um sermão específico em língua latina (o Sermão V do IV Domingo do Advento), no qual o pregador relaciona as quatro virtudes cardeais com episódios da vida e obra de Cristo, como relatadas nos Evangelhos. O tema será relacionado com algumas representações artísticas do santo: as pinturas de Joan Macip (1540-1545) e a mais famosa, de Alonso Cano (1601-1667), “São Vicente Ferrer Pregando” (1644-1645), bem como o retábulo central do altar da Igreja do convento dominicano de Cervera (Segarra, c. 1456), que representa São Vicente Ferrer e a Mãe de Deus (Virgem Apocalíptica), de Pedro García de Benabarre (1445-1485). Nossa análise iconográfica basear-se-á na perspectiva teórica de Erwin Panofsky (1892-1968), e na definição de imagem para o período conforme as considerações de Jean-Claude Schmitt (1946- ).The aim of this work is to analyze some aspects of the philosophical discourse and the medieval rethoric elements contained in the sermons of Saint Vincent Ferrer (1350-1419), especially his thoughts about a theme currently and universally present in the Christian Middle Ages: the moral virtues or cardinal virtues. For this, we will utilize a specific sermon wrote in Latin language (the Vth Sermon of the IVth Sunday of Advent), in which the preacher relates the four cardinal virtues with episodes of the life and deeds of Christ, as reported in the Gospels. The theme will be related with some artistic representations of the saint: the paintings of Joan Macip (1540-1545) and the most famous, of Alonso Cano (1601-1667), “Saint Vincent Ferrer Preaching” (1644-1645), as well as the central altarpiece of the Dominican Convent Church of Cervera (Segarra c. 1456), which represents Saint Vincent Ferrer and the Mother of God (Apocalyptic Virgin) of Pedro García de Benabarre (1445-1485). Our iconographic analysis is based on the theoretical perspective of Erwin Panofsky (1892-1968), and in the definition of image for the period according with the considerations of Jean-Claude Schmitt (1946- )
